In the swamps of Dun there lies many dangerous creatures of insect and reptilian descent. This is an area polluted with natural poisons and herbs and as such the tarlike marshes produce a lot of bad creatures that sort of "hide in plain sight" or in the ruins from the time Dun was a much more stable place (and when it was a vassal of the Kingdom of Acre, a monarchy that it declared itself independent of several centuries ago). I'm not sure if I have a bestiary of names of creatures but it's very much in the scheme of high fantasy.
